PACKAGE 0F SENSITIZED MATERIAL.

Application med March 15,192.3. Serial No. 625,241.

sensitized material and more particularly to a roll of material, atleast a part of which is sensitized, the outermost convolution of whichis secured by an adhesive sticker sheet to the next inner convolution. 1

" It is common to 4place such sticker sheets in a position entirelycovering the extreme end of the` band. In heavy rolls, as` of paper fora Commercial copying camera, these sticker sheets are made of fairlystrong material and it is not always an easy matter to tear them andstart the unrolling`of the band. The objects of this in vention aretoirnprove the method of securing the freeend f such a band, to permit`the use of a stick r of fairly strong material, and to provide a strongmanipulating tab by which such a sticker may be readily torn. These andother objects are attained by' the structure hereinafter described,`andillustrated in the accompanying drawing in which:

' Fig. 1 is a perspective view of a package secured by my improvedmeans;

"Fig.. 2 is a section of 'such' a roll showingvthei startingof theopening action;

Fig. 3 is a, plan of the end of the band before being folded; y

Fig. 4 is a similarv view showing the folded arrangement; p

Fig. 5 is an elevation of a package With a modified arrangement;

Fig. 6 is a plan of the end of a band folded as shown in Fig. 5. J

The form of package which I have chosen to illustrate my inventioncomprises a long band ofmaterial 1,'at least a p-art of which issensitized, Wound into a roll and carried on end hubs 2 which engage theinnermost convolution '3 frictionallyi and which are secured to.endnanges 4t with reinforced roiinded edges 5. the details of the spool orcoil as such are not claimed, they lneed not be further described. i

This invention relates" to a package Aof- In my preferred form the endof the band 1s cut symmetrically to form edges 6 at an angle toy theside edges 7 and meeting at a point 0. These are then bent back onthelines 0B, so that the edges 6 meet and `abut on the mid-line o f theband. The

bent over flaps lie on the underside of the band and are firmly held inposition qby the band when rolled, thourh .they may be adhesivelysecured if desirv There is thus formed a tapered end portion 9 which isstrengthened and'reinforced throughout its length by the iaps 8. 'Theangle originally made by the edges determines the angle of Vthe line 0B.when the edges 6 are ben-t to longitudinal osition, and AI have foundthe proportions s iown'to be satisfactory ferably shouldv not be as longas a complete convolution of the band, but it should be long enough toprovide a longtaper permit? ting the ready placing of a sticker sheety10 transversely thereof. The sticker sheet will be placed far enoughfrom tip 0 to leave a' tab 11 which may be easily grasped and which isstrong enough so that when -,pulled it will readily disrupt' the sheet10, even though the latter 1s made of fairly strong materlal. Thesticker. sheet is referably made of paper coated on its un ersurfacevvithan adhesive b Whichy its central ortlon 1s secured to t e taperedend 9 an its ends 16 are securedto the next inner convolution ofVband 1. shows the sheet 10 partially disrupted, one end portion 16being shown as 'in contact. With the neXt convolution, while the tab 11is carrying with it the central' Fig.

portion of the sticker sheet. As is Shown, the reinforced tabis thickerand stronger than. sheet 10. f

A modified form of'reinforced end is illustrated in Figs. 5 and.6. Theband 1 has at its end symmetricaly inclined edges 12 which are arrangedat the angle of the desired final taper, and the extreme tip 13 is bentstraight backen the line 14, transverse of the band. It is bent underthe band and may be adhesively secured if desired.,y This taperedportion of the band as used is blunt ended and only'the extreme end portion is reinforced" by the bent over portion I '15. Thisreinforcement, however, extends far enough back to form a tab ofsuiiicient The tapered portion pref' by Letters Patent is:

length for manipulation and the sticker sheet l0 will be applied at sucha position as too-verlap the turned back portion 15.

It) is to be undersood that the above described forms areto beconsidered as exam: ples of my invention, and I' contemplate as Withinthejsco'pe thereof all such modifications and equivalents as fall'Within the terms of the appended claims.

Having thus described my invention, what I claim as neu7 and'desire lto.secure l. A package of sensitized material coinprising a` rolled band',the outer end portion of which is tapered, all of said tav,

pered portion being reinforced by a double thickness formed by foldingthe material back on itself, and a sticker sheet lying across saidtapered portion, theends of 'the Vsticker sheet being secured tothe nextinner convolution of the band and constituting the sole sealing meansfor the package, the extreme end of the tapered portion extending beyondthe sticker .sheet and constituting a. manipulating tab.

2. A package of sensitized material comprisinga rolled band, the outerend ortion of which is symmetrically tapered-and reinforced, thereinforcements comprising` corner portions` folded back until theiredges meet in the mid-line of the band, and

a# sticker sheet. lying across said tapered EDWARD P. FLYNN.
